Ok so I know what most of you are thinking.. I did search and it seems as though most of the stuff both Googling and searching the forums here is rather dated. I know iwn driver is compatible with FreeBSD 8.1 however I do not know if it supports AP mode. I currently am running my pfsense box hooked to a netgear gigabit switch then a Linksys G wap, I REALLY want to ditch G. So I;m hoping that since most of the posts I've seen around regarding BSD/pfsense and N are older than mid-2011 that things have progressed and N will be easier to setup.

I did install 2.0.1 on a test box with the pciE card installed and it was not recognized. What would be the best method of getting PF to see the card? Would I need to compile it on a FreeBSD machine? Are there instructions anywhere on "installing' drivers in PF or do the generic driver installs on BSD use the same commands and methods?

FWIW: PF did recognize the card as an Atheros in my test box. I will not know the extent of it's operation until I put in into production. But even if it's not running as N, at least I wont have to change hardware when N is fully supported.

If you are looking for help to resolve this please help the readers help you by providing more information. For example, complete the sentence

In pfSense card work only in "Infrastructure (BSS)" 802.11a/b/g mode

Are you looking for a card to act as an Access Point? If so a card with the Atheros chipset should do the job fine. If I recall correctly, some readers have reported problems with some 802.11n capable cards but other readers have had a satisfactory experience with 802.11n capable cards.

Is a Centrino Advanced-N 6205 AGNThe current source code for the iwn driver should recognise this device, but the device id is not in the table of supported devices in FreeBSD 8.1 (so not in pfSense 2.0.x), nor in FreeBSD 8.2. It is in the table of supported devices for FreeBSD 9.0 and for FreeBSD 8.3 (and hence pfSense 2.1). pfSense 2.1 is not yet released but snapshot builds are available from http://snapshots.pfsense.org.

If you install (or upgrade firmware to) a snapshot build of pfSense 2.1 you will need to add it to the pool of devices pfSense uses by going to Interfaces -> (assign) and clicking on the "+" at the bottom right of the page.
